5.4.2 Motor Thermistor
Motor thermistors can be connected directly to the VLT® Soft Starter MCD 600. The soft starter trips when the resistance of the
thermistor circuit exceeds approximately 3.6 kΩ or drops below 20 Ω.
The thermistors must be wired in series. The thermistor circuit should be run in shielded cable and must be electrically isolated from
ground and all other power and control circuits.
